AD9833: 低功耗、12.65 mW、2.3 V至+5.5 V可编程波形发生器

AD9833 功能框图AD9833是一款低功耗、可编程波形发生器,能产生正弦波、三角波和方波输出。各种类型的传感、激励和时域反射仪应用都需要产生波形。输出频率和相位可通过软件进行编程,以便于调谐。无需外部元件。频率寄存器为28位;当时钟速率为25 MHz时,可以实现0.1 Hz的分辨率。同样,当时钟速率为1 MHz时,可以实现0.004 Hz的调谐分辨率。AD9833通过一个三线式串行接口写入数据。该串行接口能够以最高40 MHz时钟速率工作,并且与DSP和微控制器标准兼容。该器件采用2.3 V至5.5 V电源供电。AD9833具有省电功能(SLEEP)。当该器件的某些部分不在使用时,可以利用省电功能关断这部分,从而将器件的功耗降至最低。例如,在产生时钟输出时可以关断DAC。AD9833采用10引脚MSOP封装。

The AD9833 is a low power programmable waveform generator capable of producing sine, triangular, and square wave outputs. Waveform generation is required in various types of sensing, actuation, and time domain reflectometry applications. The output frequency and phase are software programmable, allowing easy tuning. No external components are needed. The frequency registers are 28 bits; with a 25 MHz clock rate, resolution of 0.1 Hz can be achieved. Similarly, with a 1 MHz clock rate, the AD9833 can be tuned to 0.004 Hz resolution.The AD9833 is written to via a 3-wire serial interface. This serial interface operates at clock rates up to 40 MHz and is compatible with DSP and microcontroller standards. The device operates with a power supply from 2.3 V to 5.5 V.The AD9833 has a power-down function (SLEEP). This allows sections of the device that are not being used to be powered down, thus minimizing the current consumption of the part, e.g., the DAC can be powered down when a clock output is being generated.The AD9833 is available in a 10-lead MSOP package.
